It's so easy to make Sautéed Onions for steak with this simple and foolproof method! Thinly sliced sweet or Vidalia onions are cooked in a skillet with oil and butter until golden-brown. But you don't have to stop at steak! Theymake a sweet and savory addition for burgers, chicken, dips, and so much more!
Prepare the Onions: Thinly cut onions into ¼-inch slices.
2 pounds sweet onions
Cook in a Skillet: Add olive oil and onions to a large stainless steel skillet over medium-low heat. Cook onions for 30-50 minutes, stirring every 3-5 minutes.* (In the beginning you can wait a little bit longer between stirs. Towards the end you will want to keep a close eye on the onions, to prevent burning.)
2 tablespoons olive oil, ½ teaspoon salt
Add Butter: After about 25 minutes, the onions will start to become a light yellow color. Add butter and stir to combine. You’ll know the onions are done cooking when they reach a caramel color and have a natural sweetness to them.
1 tablespoon butter, sugar, water
Serve sautéed onions with your favorite filet mignon, baked chicken, or recipe of choice.

Notes
Pan: A large stainless steel skillet conducts heat the best and helps food brown more easily than a non-stick pan.
Oil and butter: While butter adds a lot of amazing flavor to caramelized onions, it tends to burn, so a normal cooking oil should be used for the initial cooking process.
Baking soda: A pinch of baking soda can help them caramelize faster by encouraging browning, but remember that doing so will break them down and give them an almost jam-like consistency.
Liquid: There is a TON of flavor packed into the brown bits at the bottom of the pan, so be sure to deglaze with water, stock, or even alcohol like white wine for a bit of extra flavor when making this caramelized onion recipe.
